Title: Manufacture of electrolytic capacitor
Inventor: KURITA JUNICHI
IPC: H01G9/012
Filed: 1988-06-22
Abstract: PURPOSE:To improve short-circuit failure rate of products and leakage current characteristics and obtain favorable results even in an environmental test such as a heat cycle test by applying YAG pulse leser beams to a lead buried part so as to melt and unite a lead and a part of a pellet. CONSTITUTION:YAG pulse laser beams 3 are irradiated to the base of a lead wire 2 buried part at the output of 1 to 12 joule/pulse within a vacuum chamber 4 so as to fuse and unit a lead wire 2 and a part of a metallic pellet 1. If the output of laser beams added exceeds 1 joule/pulse, the pull-out strength rises and joining of an anode lead advances. Also, in case of tantalum whose melting point is 1997 deg.C, is it exceeds 12 joule/pulse, the anode lead is cut and it becomes impossible to use it as a capacitor element, so 12 joule/pulse is upper limit. Hereby, joining between the lead and the pellet becomes stout, and it can be made into a capacitor element strong against external stress, and short-circuit failure rate when it is made in a product can be reduced, and leakage current characteristics can be improved.

IPC: H01L29/78
Filed: 1992-05-22
Abstract: PURPOSE:To provide an image sensor in which an output can be stabilized by reducing an output offset and the fluctuation of the output.

Title: Circuit for correcting distortion of pulse width in optical transmission
Inventor: KOBAYASHI TASUKU
IPC: H04B10/524
Filed: 1988-06-24
Abstract: PURPOSE:To prevent erroneous data fetching and unlocking of a PLL circuit by providing a DC amplifier means and making negative feedback so that the duty ratio of output pulses from an adder means can become the duty ratio of input pulses by means of the output of the amplifying means. CONSTITUTION:PCM signals having a 50% duty ratio outputted from an optical transmitter 1 are received by means of a photoelectric converter 3 through an optical fiber 2. Since inverters IV1-IV3 have the input-output characteristics shown in the figure, the output level of the inverter IV3 becomes higher when the output of a rectifier circuit 5 drops. The increased output is added in an adder-integrator 4 and the output level of the converter 3 is substantially raised. Therefore, the potential at the input terminal of the inverter IV1 becomes the one shown in Fig. (c) and negative feedback is performed so that the potential can be raised to the average DC level when the duty ratio is 50%. As a result, the duty ratio of pulses outputted from a output terminal is pulled back toward the 50%.
